T0 whom, it may concern..-

Be it known that I, DANIEL WEETZ, a citizen of the United States, residing at Fayette, in the county of Howard and State of Missouri, have invented certain new and useful Improvements in Oar-Couplings; and I do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in car-couplings; and it consists in the novel construction, combination, and arrangement of the several parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a side view of one end of a car provided with my improved coupling. Fig. 2 is avertical longitudinal section of a draw-head with my improvement. Fig. 8 is a horizontal longitudinal section of a draw-head with my improvements.

The draw-head A may be made of any desired form, and is provided with an open mouth, a, as usual, and a horizontal mortise, (1, extended inward from said month,as shown. The coupling-pin hole Bis formed through the draw'head in the common arrangement. A mortise, G, is cut through the upper side of the draw-head and intersects mortise a at the rear end of thelatter. The bumper-block D is placed and movable in the mortise, and is provided near its rear end with a curved groove or seat, (I, for the extension of the coupling-pin arm. I prefer to form this groove in a portion or block, d, which I project upward from the bumperblock into the intersecting mortise G, as clearly shown, though it may, when so desired, be formed below said mortise, as will be appreciated. Frictionsprings E are secured at one end on the plunger-block, and bear between said block and the walls of mortise a, producing a friction sufficiently strong to prevent said block from being pushed back by the gravity of the couplingpin and arm when said pin and arm are elevated, as indicated in dotted lines, Fig. 2. These springs may be made of coil-wire or in various forms and arrangements other than that shown in Fig. 2; but I prefer to form and arrange them as therein shown.

The pin F is supported on the forward end of the coupling-pin arm G. This arm is pivoted near its rear end on the draw-head over themortise O, and is provided with an extension, ,0, depending into said mortise, and having its lower end curved and fittingsnugly the curved seat it, formed in the bumper-block, as before described. By this construction the movements of the arm G and the bumper-block D are communicated from one to the other. The arm G is preferably provided with a rear or stop extension, adapted to limit the upward movement of said arm, as will obviously appear.

In operation, when the parts are in the position shown in Fig. 1, and indicated in dotted lines, Fig. 2, if the link be pressed against the bu mper-block, it will force said block back to the position shown in Fig. 2, and cause the pin to be forced within and retain the link. I ordinarily provide the bumper with a tongue or extension, D, projected from its forward end, and adapted to rest under and support the pin when the latter is in the elevated po sition shown in Fig. 1. Such construction will give good results without the friction-springs; but I prefer to use same, as thereby the jolt ing or accidental jarring of the bumper-block out of position is prevented.

The cars may be uncoupled by raising the coupling-pin arms. This maybe done by hand or a rope, as shown, or rod may be connected with the said arm and extended to the top or side of the car, so as to enable the operation of the link therefrom. The rope H, it w ill be seen, has one end secured to the arm G, and is carried thence up through eye H to the top of the car. If desired, it could be carriedlaterally from the eye H to the side of the car, as will be readily understood. A hook, E, is secured to and projects from one side of the draw-head. The object of this hook is to support an extra link or the coupling-link when desiredas when each of the meeting drawheads is provided with a link as wilLbe readily understood.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination of the draw-head having a longitudinal mortise and a vertical intersecting mortise, a bumper-block placed in said draw head, friction spring or springs bearing between the bumper-block and the walls ofthe draw-head, the pin, and the arm supporting the pin and pivoted at or near its rear end, and provided with a depending wing or extension projected into the intersecting mortise, and connected With-the bumper block, substantially in the manner and for the purposes specified.

2. The combination of the draw-head mortised longitudinally, and provided with a vertical intersecting mortise, a bumper arranged in said draw-head, and provided near its rear end with a curved groove or seat, the spring or springs bearing between said block and the walls of the longitudinal mortise, the coupling-pin, and the pin-supporting arm pivoted DANIEL NVERTZ.
